How complete each record is

Of your 1,739,117 journal articles, how many carry each piece. These are Crossref's own published figures for your membership — anyone can look them up, including the people who assess your journals. Crossref counted them on 22 Oct 2026, 04:40 IST. It recounts about once a day, so anything deposited after that time appears at its next count.

This record as one metadata completeness score, beside large publishers and all of Crossref →

The gap list reads Crossref's live listing of your journal articles — up to 5,000 records (5 requests of 1,000, Crossref's maximum per request); a publisher with more gets the first 5,000 as Crossref lists them, and the file says so. A finished list is kept for 6 hours, so a second download inside that time asks Crossref nothing; a fresh read counts as one lookup (12 an hour from one place; 60 for a signed-in account). The file carries this table's figures and says, per element, whether the live list reproduces them.

Counted from the ISSNs Crossref has seen deposits under. A journal you publish that has never had a DOI does not appear here — which is itself worth knowing.

What this adds up to

Never deposited at all: Funder ROR IDs. Not one of your 1,739,117 journal articles carries these.

On fewer than half your records: Reference lists, Abstracts, Author affiliations, ROR IDs, ORCID iDs, Full-text links, Funding, Award numbers, Crossmark.

This page reads only what is public. It does not say whether your journals are well run — it says what a database sees when it looks you up, which is the first thing every index does.

Three questions, if you run Cambridge University Press (CUP)

Answer what you like; we reply from a person, about this record. Nothing here is shown anywhere.

3. Would you take a paid pilot on one issue?

One reply from us, about this record; privacy.

Everything Smart Scholars runsNine sites, one account. A journal starts at the audit; an author starts at Scholar Shield.

What we can register a DOI for
